So EasyHax pointed out to me that any gamelist.xml file in the roms directory will override the one in the .emulationstation/gamelists/ directories. Sure enough I found a 0 byte gamelist.xml file in the snes roms directory. It HAD to be something this simple...
Pi is very demanding on the power supply.
If the voltage is below 5.2V, turbo mode is disabled
PI will operate at a reduced frequency in throttling mode.
Some SNES games, even on an optimized driver under the SNES2002 AWS, will slow down.
@batesman hi, i have been having the same problems with my 8bitdo. Did you ever manage to fix the problem? I just got my 8bitdo today and while i was playing super mario kart it just steered me into a wall on a few occasions, then started resetting the game or just going back to the game list menu. worked 100% ok playing golden axe 3 for megadrive so only noticed it in the snes emulator.
@doctorstork I don't think anyone is bullying - perhaps some joking around due to frustration, but this is due to the way you originally posted.
I accept that you were genuinely looking for help, but it did come across originally that you hadn't read any of the documentation. When registering we ask you to read a post which details information you should provide before posting, and you didn't provide any of that.
We also have had a lot of trolling in the past - I appreciate that you were not intentionally trying to be difficult, but it did come across that way earlier on.
We have a lot of people asking the same questions over and over again, and most of the time it is because they have not read the instructions before installing, or the guidance before posting. And probably because they have purchased retropie from an unscrupulous seller who was quick to take their money.
Hang around here, and you will appreciate the time everyone puts in to help others. My post count is in the thousands, and it's all answering user questions, and unfortunately mostly posting the read me first link again and again.
Your are welcome here - but we don't have time to continually re-iterate the information we have already painstakingly documented. Stay a while, perhaps share some of what you have learnt with others, and you will have a better understanding of the project.
Adding to what @MagiusRetro said, you could also have the settings he mentioned applied on a per-game basis to avoid having to deal with the drawbacks in all your other games. More information can be found at the link below.
